python label内容靠左 python label属性

Label是标签

用法

　　Label(根对象, [属性列表])

属性

• text　   要现实的文本
• bg　　  背景颜色
• font　   字体(颜色, 大小)
• width　 控件宽度
• height　控件高度

控件属性设置有三种方式：

　　1.创建对象时，指定宽度与高度

　　2.使用属性width和height来指定宽度与高度

　　3.使用configure或config方法来指定宽度与高度

　　以上三种方式效果相同。

# -*- coding: utf-8 -*-
from Tkinter import *

root = Tk()
one = Label(root, text='one', width=30, height=1,bg="green", font=("Arial", 12))
one.pack()

two = Label(root, text='two',bg="red", font=("Arial", 12))
two['width'] = 30
two['height'] = 2
two.pack()

three = Label(root, text='three',bg="blue", font=("Arial", 12))
three.configure(width=30, height=3)
three.pack()

root.mainloop()

结果显示如下：

调整代码，让三个label同列显示：

# -*- coding: utf-8 -*-
from Tkinter import *

root = Tk()
one = Label(root, text='one', width=30, height=1,bg="green", font=("Arial", 12))
one.pack(side=LEFT) #这里的side可以赋值为LEFT  RTGHT TOP  BOTTOM

two = Label(root, text='two',bg="red", font=("Arial", 12))
two['width'] = 30
two['height'] = 2
two.pack(side=RIGHT)

three = Label(root, text='three',bg="blue", font=("Arial", 12))
three.configure(width=30, height=3)
three.pack()

root.mainloop()

显示效果：

 

最后设置好Tkinter窗口的大小属性，一起看看效果

# -*- coding: utf-8 -*-
from Tkinter import *

root = Tk()

root.title("hello world")
root.geometry('800x600')
root.resizable(width=False, height=False)
one = Label(root, text='one', width=30, height=1,bg="green", font=("Arial", 12))
one.pack(side=LEFT) #这里的side可以赋值为LEFT  RTGHT TOP  BOTTOM

two = Label(root, text='two',bg="red", font=("Arial", 12))
two['width'] = 30
two['height'] = 2
two.pack(side=RIGHT)

three = Label(root, text='three',bg="blue", font=("Arial", 12))
three.configure(width=30, height=3)
three.pack()

root.mainloop()

显示效果如下：
